Gliese 754

Gliese 754 is a red dwarf star of spectral type M4.5V in the constellation Telescopium.[1] It has an apparent magnitude of 12.23 and is around 19.3 light-years distant.[1] It is one of the hundred closest stars to the Solar System. Calculations of its orbit around the Milky Way showed that it was eccentric, and indicate that it might be a thick disk object.[2]

gollark: For all that tailscale fairly good it is probably not ideal on *really* resource-constrained systems.
gollark: (it does not run any software except tailscale and sshd)
gollark: (30MB of which is tailscale)
gollark: Anyway, Alpine is quite minimal, I think. All the processes conveniently fit onto my screen in htop (half are just tailscale ones), and it's using 52MB of memory.
gollark: (Pis before the Raspberry Pi 3 *do not* exist.)
